rotor earth fault alarm comes only if our carbon brushes
become earthed. it may be at the time of changing carbon
brushes.

Is there any problem about which the drive (inverter) doesn't show/display the alarm and/or fault but instead of this , it doesn't work ? I want to know that could there be any kind of problem in the drive when the drive doesn't display the alarm and/or fault ?
